Personal backup appliance (pba) is a great free open source imaging tool.

Using PBA is a quick way to create and restore images.

What took me one hour to create and restore image by using Symantec Ghost, it takes me under 10 minutes with PBA.

Installed Ubuntu on USB jump drive.

Copied pba client to the drive from PBA server.

When running pba.sh was getting the following error message “dialog not found.  PBA cannot start”

“dialog” is not installed by default on ubuntu USB

Running apt-get install dialog have resolved the issue with pba client on Ubuntu.

Using postfix as POP3 on Ubuntu

install postfix

apt-get install postfix

If you are not able to telnet on port 25 to your postfix server
check your /etc/postfix/main.cf and make sure that inet_interfaces is listening on all network interfaces
and not only local by disabling #inet_interfaces = loopback-only or you can remove this line completely.

Installed dovecot (POP3/IMAP) on Ubuntu

apt-get install dovecot-imapd dovecot-pop3d
Now you should be able to configure youemail client (Thunderbird, Outlook,etc.) with your postfix server
to send and receive email.

In my case I did install postfix and dovecot on my home linux server and configured Thunderbird as mail client to send and receive email messages.

Here is a great reference on how to install Dovecot

https://help.ubuntu.com/community/Dovecot

nano /etc/network/interfaces

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.104
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1

And save it.

Now move on to edit the /etc/resolv.conf.

And add the name server.

nameserver 192.168.1.1

Another way to configure static IP address
ifconfig eth0 192.168.1.104 netmask 255.255.255.0 up

Running as root fixed the problem…

sudo passwd root

sudo -s -H
